`To ZZ momia my @mmf i v'Be it1known thatI, WILLIAivLS'rliLE, of e, Wheeling, i inuthe `county of Ohio and State of1Vir .inia, have inventedsundrynew and useful 3, Inprovementsin TenonlngMachines y and :I do :hereby declare that the" following isafull and exact"descriptionthereof, refer-` ence being had@ to the `lacconnoanying drawings, making part zofvthis specification. e The nature of Vmy` invention consists, `first,

measured upon the* timber to be operated upon, and `thenfthe timber` be fed up to the :tenoning chisels` -`by means of `a ratchet handle (a) jointedstothe said metallic base (pyand au ratchet (0) secured to the `Side ofthe said box (Hb 'e V'lhesecond eatureof invention, consists in the combination of the base p, of the feeding' boxH,"` and fof the rest s, with one 'ender posts 1n such a manner that the said base and rest` can be secured 1n an f oblique position to the `fender post-s and to .y the" movements ofthe tenoning cutters,when `everV iturnay bedesired to form tenons with oblique shoulders.`

`1 The third feature ofmyinventiom con-* j `sists in combining incision cutters `with the e "tenoning cutters insuch a manner that the incision cutterswill penetrate into the surface of thewood and prevent the tenonin cutters, which follow them, from tearing lo fsplinters from `the sides of the timber operated upon.

The frame of ItenoningY machine, is composedjof the uprights Y, Z,`which have `their upper ends united toeach other, and

theirllowerends secured ina suitable base.

A rectangular metallic `trame A`,;secured lto the upright y, receivesthe gate C,in which the incision cuttersml, Z, and the tenoning cutters j, j, are secured `the sides of the said C, to play upon.` Downward motion is imt. parted to the gate C, by means of the treadle E, and the pitman D ,and upward motion is 3f 5o v imparted tosfaid gate, by the cordm, which is "connected tot the treadle` E, and thence "passes over the pulley F, to the spring bar Or the said gatefmay be operated by.` powerin any "usual orwell-.knownmannen f* i The tenoning cutters j, j, and the incision Htiratoririre-1yr)tourna 412,449, dated February 2'?, 18u55.

cuttersj'l, Z, are securedv in recesses in the enlargements C, C', at the upper end of the gate C, by means of theplates 71,121, and the set screws i, z', as shownin Figures 2, and 5. The shape of the right angular cutting edges of the tenoning cutters is shown in Fig. 6,

" i wInLIM srELEfoFvwHEEILiNG, VIRGINIA The end cutting edges of the tenoning cut- `ters operate upon the sides of atenon, `and the side cutting edges of said cutters operate upon the shoulders of said tenons. The tenoning cutters areconsequently so arranged that their end cutting edges will be separated Vfrom each other a distance exactly the same as'that of `the required thickness ofthe tenori` to be formed. `And the incision cut- `,ters Z, Z, are. arranged in such positions that I they wiil cut into the sides of the pieces of `joist operated upon, a suflicient distance to prevent the action of the side cut-ting edges of the tenoning cutters from tearing splinters fromvthe sides of said joist. The metallic base p, of the rest s, and of the gage box H, is secured to the frame A, in the following manner, viz: a sliding box d, having a Wing g, secured to one of its sides, is connected to the innermost side of the said frame A, by means of a broad headed set screw e, that passes through a slot inthe said side of A, and through the face of the box cl, and that has a nut L, upon its outer end that bears against the face of d, by

which the said box can be moved up or `down and secured in any desired position-` upon the said side of A. The base p, of the gage box H, and of the rest s, has a segment shaped wing 76, secured to its inner end,

` which wing is brought in contact with the `wing g, of the box d, and secured thereto by means of the joint pin n, and t-he set screw f, as shown in Figs. l and 3. The said set screw f, passes through a curved slot in the Wing k, and into a screw aperture in the `wing g and consequently, as the said wing 7c, is connected to the wing g, by a joint pin,

`the base p, `(which is connected to 70,) `can be secured to the box d, in a position at right angles tothe sides of the frame A, or in an 1 oblique position thereto.

When a piece of joist is placed in the gage box H, to have a tenon formed upon one of its ends, the forward end of said poist is movedV forward until it is brought `in contact with the tenoning cutters, and then the gage box is moved outward from the rest s, a distance exactly equal to that of the required lengt-h of the tenon to be formed; the said joist is then secured in the box by the set screw J, and is fed forward to the cutters by means of reciprocating movements imparted to the hand lever a; the said lever being pivoted to the under side of the base p, and having a curved pawl b, risingfrom it and working into the teeth of the rack c, that is secured to the front side of the box H. The height of the base p, of the box I-I, and of the rest s, is adapted to the depth of the joist to be operated upon, so that there need not be an unnecessary amount of motion imparted to t-he tenoning chisels.

v In the accompanying drawings Fig. 4, is a horizontal section in the line w, of Fig. 1, and Fig. 5, is a vertical section in the line a, a, of Fig. 3.

That I claim as my invention and desire to secure by Letters Patent, is

l. The arrangement of the feeding box H, the rest s, and their base p, with each other and with the gate C, which carries thetenoning cutters, in such a manner that the said feeding box may be moved from the said rest, upon the base p, the desired length of a tenen, and then be fed forward again, to bring the joist to be operated upon in contact with the cutters, substantially as herein set forth.

2. I also claim combining the base p, of

the feeding box H, and of the rest s, with lthe frame A, in such a manner that the said base, box, and rest, can be secured in an oblique position to the sides of said frame, and tothe direction of the movements of the tenoning cutters, whenever it may be desired to form tenons with oblique shoulders in the manner set forth, or its equivalent.

3. I also claim the combination of the incision cutters Z, Z, with the angular edged cutters j, y', in such a manner that the said incision cutters will penetrate into the surface of the wood, in advance of the tenoning cutters, a suflicient distance to prevent the said edges of the tenoning cutters from tearing out splinters from the sides of the tim# ber operated upon. f

The above specication 'of my improved tenoning machine signed and witnessed this twenty rst day of November 1854.
